My Lifan and Zongshen owners manuals say 93 and 91 octane but they're using the European rating instead of the US rating. Equivalent in the US is about 87 octane regular. Using premium or mid grade won't hurt but regular 87 should be fine. If it doesn't ping, all is good.

Hmm, good point. They probably are using Euro grades. Maybe I'll try a little bit of 87 and see what happens.

Another question. Have any of you had the issue of the engine bogging down past half throttle? Like it's not able to ignite all the gas or something. Or maybe it's getting too little gas. Unsure, but there is definitely a loss of power if I roll the throttle hard past half. Thoughts?

I believe there are some threads addressing that issue on the Hawk. Usually a matter of jetting and airflow that can be fixed without too much bother.

Changing out the main jet to a #110 and the air box mod are a big improvement. Motocheez has YouTube videos on how to do it. Also check your valve clearance. May need adjusting.

Can't Sleep - Hawk Should Be Here Today!

So I can't sleep. Big surprise, considering the freight company called me on Wednesday and set up my delivery appointment for today between 2:00 and 5:00 pm. This is my excited face! I got the new 17t front sprocket and 39t rear sprocket (I may buy a larger rear sprocket if the 39t saps too much power), as well as a seat pad and carb jets in yesterday's mail. I also have digital cluster from Matt coming in today. I have parts already and don't even have the bike yet...
I was out in Vegas on vacation this past week, and had to reflect on the wonderful world we live in: I was in a casino with the wife I don't deserve, and my awesome inlaws, and ordered a new motorcycle using my cell phone while sitting in front of a blackjack game. I ordered from TXPowersports.com, and so far the experience has been adequate. There wasn't a ton of communication back and forth, just the routine order received and order shipped emails. The only minor complaint I have so far is that there wasn't any tracking info on the order. Not the end of the world, I just like being able to watch the package progress. I'll keep everyone posted once I get the bike unpacked and assembled. I have to go to the DMV to register the other vehicles, so I'll also update what has to happen out here in Carrollton to get a plate. Have a great day, everyone.

Awesome! Hope it all goes well for you. Man you went all in! haha. I need to up my game on upgrades.
I'm interested to see what the DMV has you do. For me I got different answers every time I went in. I still haven't gotten my title back from the state. I'll see if they require something more to be done.

A New Hawk Is Born!

IT'S ALIVE!! After a friday spent unexpectedly laying new tile in my kitchen (very long story), I have been able to spend today assembling the Hawk. First impressions:
1 - The hawk should really have a comprehensive manual for assembly. I have a bag of nuts, bolts and washers left over, as well as some grommets and wire keepers.
2 - TXPowersports did an excellent job with the order, however UPS Freight was a little lacking. I had to hook up my trailer and go meet the truck. He was in a full size rig, after I told the dispatcher that they would need a pup truck to get into my neighborhood. In any event, I did wind up getting the crate on the day it was scheduled, just had to go a little out of my way for it.
3 - Did I mention an assembly and instruction manual??
4 - The bike starts and runs, but once you get past about 1/2 throttle it starts sputtering and bucking. I have the jets and some washers, I think I'm going to take the carb apart and start playing around.
5 - I installed the digital cluster from Matt (hawkClusters@Gmailcom) and I'm very impressed. I need to tinker with it a bit to get it to face me more directly, and it seems to be canted a little to the right. I have a hacksaw and a welding torch, what could possibly go wrong?
6 - So, about that manual...
7 - The tires are super aggressive on the street, and you can count every knob as they roll over. Haven't decided if I'm going to burn these ones out and go with something a little more street friendly, or keep the bike set up for fun out in the woods. More to follow...
8 - SET THE VALVES!! My rig came from the factory with a valve clearance of 0.00. I set them for 0.05 and they seem to be happy. Noisy, but happy.
9 - I ran it for a few minutes with the oil from the factory to get it warm, and then changed it right away. I used Suzuki 10w40 because that's what I have for the DR. Seems to work well.
10 - Ten bullet points, really? Get on with it already and start a new thread!
11 - DMV will need to wait until Monday, but I'll get back about that. I'm going to heat cycle the engine one more time to finish the break in, then get new sprockets tossed on. Have a fantastic weekend everyone!

Very interested in your DMV experience. Please keep us posted. I'm in GA and close to pulling the trigger on a hawk but seems it's hit or miss here with getting a tag.
